Advantages And Functions of Deep Groove Ball Bearing

Press Release   •   Aug 04, 2012 16:11 IST

The deep groove ball bearing is used in various appliances like fans and motors, industrial machinery and in automobile wheels. It is made up of a pair of ferrules, a group of retainers and rigid spheres. It has the advantage of offering support to the pure radial load along with the radial load and axial load. Deep grove ball bearing has a negligible friction coefficient and quick limit speed compared to other ball beatings, especially while dealing with a very large axial load.

The bearing has the simple structure and can ensure a high manufacturing accuracy. Some of the common variants of deep groove ball bearings include those with dust cap, rubber sealing ring or a snap. Compared to other kinds of bearing products of the same size, the deep groove ball bearing will have very low friction but a high rotating speed. In addition, they can replace thrust ball bearings to support axial loads under very high rotation speed. Timely maintenance is very crucial in ensuring the maximum life span of these products. There are various categories of deep groove ball bearing and the basic model consists of an outer ring, an inner ring, steel balls and cages.

They can bear very large axial load and can function as angular contact ball bearing when the radial internal clearance of bearing is increased. On installing in the shaft they can limit the axial displacement of the shaft or housing in both directions within the axial clearance, thereby ensuring axial positioning in two directions. Another advantage of deep groove ball bearing is their relatively low cost of production.

These types of bearing products are well suited for operations requiring high speed and high rotation. They are highly durable, have very low friction coefficient and low production costs. Double groove ball bearing products are available in various sizes and models to cater to the different requirements.

Buying Tips :

Make sure that the deep groove ball bearing is made of chrome steel or high temperature. Before buying it is highly recommended to verify the maintenance requirement and the service life, which will help in arriving at the overall cost of the bearing.

There are various types of Deep Groove Bearings like Sealed, Low Friction, Small Shielded and large Shielded. Sealed types are manufactured from synthetic rubber and oil with the sheet steel reinforcement and it can be used in a wide range of temperatures between -40° C to 120° C. Low friction seal types can also operate between the same temperature ranges as the sealed ones. Small shielded ones have a sheet steel shield and have a long sealing gap where as large shielded type lacks cylindrical section and is used in operations where the rotation of the inner ring is required.


Deep Groove Bearing can carry extra load in the form of radial, composite and axial load. These have minimum maintenance, low cost and have a longer life span.
